Application filed June 19, 1903. Serial nascent To all whom it mayconcern: Be it known that I, Nine 1). LEVIN, HCllll- 'zen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have lnvented certain new and useful Improvements inMotor-Vehicles, of which the following isa specification.

The invention relates to motor vehicles,

I and particularly electric locomotives. The

invention has for its primary objects, the provision of a constructionwherein the axles are free to move independent of the frame withoutinterference with the mechanism for driving the wheels, and transmittingaminimum of such. movement to the body of the vehicle; the provision ofan improved means for flexibly mounting the motor; and the provision ofan improved and simplified Figure 3.1s an enlarged detail section online III- II of Figure 1.

Referring to the drawings, 1 is the body of the locomotive, 2 is anelectric motor, 3 is the trolley pole, 4 is the controller, 5 is thetrolley wire, Sand 7 are the axles, which axles carry the wheels 8 andare journaled in the independent wheel frames, 99, one

' the frannngor of which is mounted on each side of the body of thevehicle.

10 are springs interposedbetween the frames 9-9 and the body 1, 11 is acounter shaft mounted upon the fran1es 99, 12' and 13 are spur gearskeyed respectively to the shafts 6 and 7, 14 is a spur gear keyed to thecountershaft 11 and meshing with the gears 12 and 13, 15 is a shaftjournaled in the motor casing and carrying the gears .16 and 17, whichmesh respectively with the spur gear 13, and with the driving pinion 18of the motor, and 19 is a spring for resiliently supporting one side ofthe motor from body 1, the other side of the motor being extended toconstitute the hearing 20, which bearing incloses the axle 7,

thus giving apivotal support to the motor {in one side of its axis, anda spring support on the other side.

The ends of the axles 6 and 7 and of the counter-shaft 11-are mountedfor universal movement in the framing 9-9 in the man- I nor indicated inenlarged detail inFigure 3. As here shown the journal-box 21 is made inspherical shape and fits in rounded recesses in the casing 22 andcap-23,lw hich members are secured to the frame 9. This arrangementpermits a certain amount of movement of the axles with respect to theframing as the wheelsfollow irregularities in the track. The vibrationof" the f body of the vehicle is in this manner largely reduced, as thewheels and axles may tilt a certain amount without transmitting thetilting to the body. ear on thejournals and on the boxes is also greatlyreduced, as the. boxes twist with the axles, and there is no unduestrain or wear thrown upon the contacting surfaces by reason of bindingwhen the irregularities in the road-bed tendto throw the axles out oftheir normalposition with respect to the framing.

As shown in Figure 1.,the 12: 18 and 1 1 are provided with what maybetermed rounded teeth, that is the teeth are thickest at their centralportionand taper to the edges. The purpose of this -tooth-constructionis to permit a proper, engagement of the gears even when the" axlesaremoved out of parallelism. It will be seen that the universal mountingof the shafts Sand 7 requires some such .tooth construction, as

otherwise the engagementbetween the gears would have to be very loose,or else such gears would be broken when theshafting shifted thusthrowing the gears out of the same plane. By the arrangement illustrateda proper driving connection is always maintained between the gears, andtheymay be shifted with respect-to each other without injury to theteeth.

By pivotally supporting the motor framing at 20 upon the axle 7, theproper relation between the axles 7 and 15 isalways maintained,'-and theflexible mounting of the motor on its rear side at 19 relieves the motorparts of undue jar also relieves the frame 1 of the strain which wouldotherwise be incident to rigidly supporting the motor.

Having thus described my invention and illustrated its use,'what Iclaimas new and desire to secure by Letters Patent is the following 1.In combinationin a motor vehicle, a

frame, two sets of journal boxes mounted for universal movement in theframe, an axle journaled in each set of boxes, a spur gear with roundedteeth on each axle, a

counter-shaft intermediate the axles carry ing a spur gear with roundedteeth engaging the spur gears on the axles,and drive means for one ofthe spur gears on the axles.

2. In combination in a motor vehicle, a frame, three sets of journalboxes mounted for universar movement in the frame, a shaft journaled ineach set of boxes, wheels and an intermediate spur gear with roundedteeth on each of the end shafts, and a spur gear with rounded teeth onthe third shaft in engagement with the spur gears on the other shaftsand means for driving one of the spur gears.

3. In combination in a motor vehicle, a frame, a driving motor, av pairof driving axles each provided with a pair of flanged wheels,universally mounted journal boxes carrying the axles, a counter-shaftbetween the axles, spur gears on the axles, and a spur gear on thecounter-shaft, such gears having rounded teeth and a driving connectionwith the motor.

4. In combination in a motor vehicle, a frame, a driving motor, a pairof driving axles each provided with a pair of flanged wheels,universally mounted journal boxes carrying the axles, a counter-shaftbetween the axles, universally mounted journal boxes therefor, spurgears on the axles, and a spur gear on the counter-shaft, such gearshaving rounded teeth and a driving connection with the motor.

5. In combination in a motor vehicle, a body frame, auxiliary frames oneach side of the body frame, a journal box mounted. for universalmovement in each of the auxiliary frames, an axle journaled in the boxesand carrying drive wheels and a driving member, and a driving mechanismengaging the driving member.

6. In combination in a motor vehicle, a body frame, auxiliary frames oneach side of the body frame, two sets of journal boxes mounted foruniversal movement in the auxiliary frames, an axle journaled in each ofthe sets of the boxes and carrying drive heels and a' driving member,and a driving mechanism engaging one of the driving members.

7. In combination in a motor vehicle, a body frame, auxiliary frames oneach side of the body frame, two sets of journal boxes mounted foruniversal movement in the mixiliary frames, an axle journaled in each ofthe sets of the boxes and carrying drive wheels and a driving member, acountershaft intermediate the axles carrying a driving member, and adriving mechanism on- .gaging one of the driving members.

frame, two sets of journal boxes mounted for universal movement in theframe, an axle journaled in each set of boxes, a spur gear on each axle,a countershaft intermediate the axles carrying a spur gear engaging thespur gears on the axles, and drive means for one of the spur gears onthe axles.

10. In combination in a motor vehicle, a frame, three sets of journal.boxes mounted for universal movement in the frame, a shaft journaled ineach set of boxes, wheels and an intermediate spur gear on each of theend shaft, and a spur gear on the third shaft in engagement with thespur gears on the other shafts and means for driving one of the spurgears.

11. In combination in a motor vehicle, a plurality of Wheel framesadapted to move relatively to each other, oppositely disposed journalboxes mounted for universal movemei'it in a pair of said frames, an axlej ournalcd in said boxes and carrying a drive wheel and means fordriving the drive wheel.

12. In combination in a motor vehicle, a plurality of wheel framesadapted to move relatively to each other, oppositely disposed journalboxes mounted for universal movement in a pair of said frames, an axlejournaled in said boxes and carrying a pair of wheels.

In testimony whereof I have hereunto signed my name in the presence ofthe two subscribed witnesses.
